Based on the classic rabbinic interpretation of this text, a day in the rabbinic Hebrew calendar runs from sunset (start of "the evening") to the next sunset.In most populated parts of the world this is always approximately 24 standard hours, but, depending on the season of the year, it can be slightly less or slightly more.Maimonides' work also replaced counting "years since the destruction of the Temple" with the modern creation-era Anno Mundi.
The time between true sunset and the time when the three stars are visible (known as 'tzait ha'kochavim') is known as 'bein hashmashot', and there are differences of opinion as to which day it falls into for some uses.
Until the Tannaitic period (approximately 10–220 CE), the calendar employed a new crescent moon, with an additional month normally added every two or three years to correct for the difference between twelve lunar months and the solar year.
When to add it was based on observation of natural agriculture-related events in Israel.
Through the Amoraic period (200–500 CE) and into the Geonic period, this system was gradually displaced by the mathematical rules used today.
The principles and rules were fully codified by Maimonides in the Mishneh Torah in the 12th century.
